Hello, I see some interesting behavior. When I do: (cl-cairo2:create-xlib-context 600 400 :window-name "gomer") I get a window alright, but the content is a scrambled image (even though I didn't start any painting). Sometimes, I don't get a scrambled image, but rather an image that was "recently" displayed on my computer (e.g. from web browser, or from the splash screen of an application). Is this expected?
